fmnctured, apical margin testaceous. Beneath black, densely punctured, two 

 ast segments of the abdomen and feet yellow : the abdominal plates are nearly 

 as long as the segment, smooth, except at base, and extend to the parapleurse.

IScymnus {Pullus) creperus Muls. Coce. 985. 



Georgia and Rocky Mountains. Very similar to the last species, differs only 

 in the punctures of the elytra being larger and less dense, and the spot on the 

 thorax less defined, reaching nearly to the apex. The abdominal plates are as 

 in the last, smooth, except at base. I do not feel certain that this is really 

 Mulsant's species; it agrees better with his S. fa s t i g i a tu s, (936) but the 

 abdominal plates are distinctly shorter than the segment.

Scym7i7ts ca?cdalisll^ec. 1. c. 238. 



One naale specimen, Lake Superior. Broadly oval, convex, black, covered 

 with dense gray hair; head and thorax finely and sparsely punctulate, yellow, 

 the latter with a large ill-defined black spot, occupying half the base, and ex- 

 tending nearly to the apex, sides rounded, base margined, obtuse in the middle, 

 oblique each side. Elytra tolerably densely, not deeply punctured, apical mar- 

 gin testaceous. Beneath black, densely punctured, abdominal plates almost 

 reaching the posterior margin of the segment, densely punctured, smooth only at 

 the inner margin, tip of the abdomen testaceous. Feet yellow. 



This may be S. fastigiatus, Muls., but as he does not mention the sculp- 

 ture of the thorax, or abdominal plates, I cannot be certain of its identity. I 

 erroneously considered this as the male of the preceding species.

One female, Upper Mississippi. Broadly oVal, convex, black, covered with 

 gray hair. Head finely punctured, mouth testaceous. Thorax black, with a 

 small yellow spot at the anterior angles, finely and densely punctured, margined 

 at the base, which is obtuse in the middle and obliquely sinuate each side. 

 Elytra densely punctured, with a narrow testaceous apical margin. Beneath 

 black, densely punctured, abdominal plates extending almost to the posterior 

 margin of the segment, punctured, smooth towards the inner margin. Sides and 

 tip of the abdomen, tibis and tarsi ferruginous ; femora piceous. 



20. S, c e r vi c alis, rotundato-ovalis, convexus, breviter dense pubescens, 

 niger, capite thoraceque rufis vix subtiliter punctulatis, elytris confertim punc- 

 tatis, apice angustissima, ano, pedibusque rufis. Long. '085. 



Muls. Cocc. 984. 



Common in the Southern States. Rounded, oval, convex, covered with short 

 gray hair. Head very sparsely and finely punctulate, rufous. Thorax rufous, 

 scarcely punctulate, base margined, obliquely subsinuate each side, obtuse in 

 the middle. Elytra shining black, tolerably densely punctured, extreme apical 

 margin testaceous. Beneath black, coarsely punctured, last joint of the abdo- 

 men rufo-piceous : abdominal plates a little shorter than the segment, smooth, 

 punctured at base. Feet rufous. 



21. S. s c er, rotundato-ovalis, convexus, breviter pubescens, niger, capite 

 thoraceque parce punctulatis, rufis, hoc macula basali nigra, elytris minus dense 

 punctatis, apice angustissima, abdominis apice, pedibusque flavis. Long. '07. 



Georgia, one specimen. Very similar to S. cervicalis, but smaller, and less 

 densely punctured on the elytra. Rounded oval, convex, covered A\ith short 

 gray hair. Head and thorax very sparsely and finely punctured, rufous, the lat- 

 ter with a large black spot occupying more than half the base and reaching 

 nearly to the apex; base margined, obtuse in the middle, oblique and scarcely 

 sinuated each side. Elytra distinctly punctured, black, shining, with the ex-
